Frequency generator with MAX038

Frequency generator or function generator is a signal generator of various shapes commonly used for electronic or acoustic equipment testing and debugging.

This frequency generator is based on MAX038 circuit from Maxim-IC and is controlled with PIC16F877 microcontroller. MAX038 circuit is able to generate signals with frequency of up to 20MHz which is pretty enough for most applications. Current signal being generated with this unit is displayed on character LCD. Project schematics is unfortunately not available but PCB, PCB with placed components diagram and HEX file is available for download on project page.
